And in fact in this case, since it known that the string will not be
modified, using this form of initialization actually improves the memory
usage of the application, because the string will live in read-only
(code segment, etc.) memory, instead of writable (data segment) memory.
When the program forks, the pages containing the code/constant
strings/etc. are not duplicated, because they are not writable.
